<h2>What does a camshaft adjuster do?</h2>
Camshaft adjusters are like the conductor of an orchestra, ensuring that the engine's components, such as the valves, work in harmony to produce power and efficiency while driving your car. These components are part of the engine's variable valve timing (VVT) system, which adjusts the timing of the camshaft to match the driving conditions, whether you're accelerating, cruising, or idling.
By adjusting the camshaft's timing, camshaft adjusters help your car achieve better fuel economy, reduced emissions, and improved overall performance, making your driving experience more enjoyable and environmentally friendly. Camshaft adjusters&nbsp;are a vital part of modern engines and play a significant role in enhancing your vehicle's efficiency and power output.
<h2>Camshaft adjuster failure symptoms</h2>
The specific failure symptoms of a camshaft adjuster&nbsp;may vary depending on the type of adjuster (mechanical, electric, hydraulic) and the make and model of the vehicle, but you may have some clues by referring to these:
Reduced Engine Performance: Decreased power, sluggish acceleration, and poor responsiveness.
<ul>
<li>Rough idling: Engine vibrations or shaking when the car is stationary.</li>
<li>Check engine light: Illumination of the check engine light on the dashboard.</li>
<li>Poor fuel efficiency: Reduced miles per gallon (mpg) and increased fuel consumption.</li>
<li>Excessive emissions: Failing emissions tests or higher pollutant output.</li>
<li>Loud engine noise: Unusual or loud engine noises like ticking, rattling, or knocking.</li>
<li>Stalling or poor idle: The engine stalls or struggles to maintain a stable idle, especially when cold.</li>
<li>Reduced engine efficiency: Gradual decline in engine efficiency and potential for further damage.</li>
</ul>
